Based on my personal experience I own a Dell 24" with 1920x1200 resolution.

All the text and icons are so small and I have to zoom webpages and increase my dpi to 150%.

So I suppose, if you use a 4K monitor, things will be much smaller, right?

Huh? I have a 24" monitor with that resolution (Dell U2412M) and it's the reference size: 96 DPI. That is exactly what 100% scaling in Windows is meant for.

If you think things are too small at that size you really need to get your eyesight checked or you're just sitting way too far. 96 DPI used to be the golden standard for monitors and is what Windows uses as default DPI.

I have a 1600x900 panel in my 13.1" laptop (140 DPI) and I love it. Things are a bit smaller, sure, but there's so much space on your display! Multitasking!

A good way to check ideal DPI settings is with Word. At 100% zoom the page on your display should be exactly as big as a real page (of that paper size). Or as close as possible anyway.

We have the same monitor, I don't think my eyesight is bad, maybe is the distance, I'm sitting one meter away from the monitor. How far are you sitting?
